Vehicles指交通工具类,交通工具有很多子类。
public class Vehicles { private String brand; private String color; public Vehicles() {} public Vehicles(String brand,String color) { this.brand = brand; this.color = color; } public String getBrand() { return brand; } public void setBrand(String brand) { this.brand = brand; } public String getColor() { return color; } public void setColor(String color) { this.color = color; } public void run() { System.out.println("我已经开动"); } public void showInfo() { System.out.println("商标:"+brand+",颜色:" + color); } }
public class Car extends Vehicles{ private int seats; public int getSeats() { return seats; } public Car() {} public Car(String brand,String color,int seats) { super(brand,color); this.seats = seats; } public void setSeats(int seats) { this.seats = seats; } public void showCar() { super.showInfo(); System.out.println("座位数:"+seats); } }
public class Truck extends Vehicles{ private float load; public Truck() {} public Truck(String brand,String color,float load) { super(brand,color); this.load = load; } public float getLoad() { return load; } public void setLoad(float load) { this.load = load; } public void showTruck() { super.showInfo(); System.out.println("载重量:" + load); } }
